3 hour glucose test

So I took my 1 hour test last Saturday and failed with a 142. I was sent today for my 3 hour. I had my first blood draw and stand the sugary drink. It went down easy and I sat for about 50 minutes. I got extremely hot, shakes and nauseous. I passed out and threw up. The lady at the lab ended my test and I had my husband come get me. They said they would call my doctor on Monday and send the first blood draw which I assume was my fasting blood sugar level. Any insights on my next steps? Will they have me do it again?
